5-3x-\left(-10\right)=60
Hei kimi i te tauaro o 3x-10, kimihia te tauaro o ia taurangi.
5-3x+10=60
Ko te tauaro o -10 ko 10.
15-3x=60
Tāpirihia te 5 ki te 10, ka 15.
-3x=60-15
Tangohia te 15 mai i ngā taha e rua.
-3x=45
Tangohia te 15 i te 60, ka 45.
x=\frac{45}{-3}
Whakawehea ngā taha e rua ki te -3.
x=-15
Whakawehea te 45 ki te -3, kia riro ko -15.
